WARMING DEVICE.

SPECIFICATION forming part of Letters Patent No. 502,370, dated August 1, 1893.

Application filed October 19, 1892. Serial No. 449,406. (No model.)

To a/ZZ whom it may concern.-

Be it known that I, FRED LIED, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Warming Devices, of which the following is a specification.

My invention relates to the improvement of portable foot-warmers and the objects of my invention are to provide a sim ple, reliable and effective device of this class of such construction and arrangement of parts as to admit of the same being conveniently carried or located; to provide in connection therewith an improved burner and to produce other improvements which will be more specifically pointed out hereinafter. These objects I accomplish in the manner illustrated in the accompanying drawings, in which- Figure l is a plan view of my improved warming device, showing in full lines the position of the burner and oil reservoir when swung outward from the heat reservoir, and showing in dotted lines said partsin position for use. Fig. 2 is aside elevation of the same showing the oil tank and burner in position for use. Fig. 3 is a tranverse section on line mmof Fig. 1. Fig. 4 is a central longitudinal section of the burner body. Fig. 5 isa transverse section on line z e' of Fig. 4 and Fig. 6 is a transverse section on line fy y of Fig. 4.

Similarletters refer to similar parts throughout the several views.

a, represents an oblong box or reservoir, which as hereinafter described, is adapted to expel the desired heat for warming purposes. Entering this reservoir a at one end thereof, which for convenience I will term the rear end and adjoining one side thereof, isalame tube a which extending to a point in the forward portion of the box has leading from said inner termination a smaller heat line or pipe a2. This pipe a2 as shown in dotted lines in Fig. l of the drawings and in section in Fig. 3 thereof, is made to pass back and forth or double upon itself the desired number of times within the remaining portion of the reservoir, preferably terminates near the diagonally opposite corner of said box from the entrance of said ame tube. At this inner termination, said pipe 0.2 is provided with an upward extension a3 which passes outward through the box top in the form of a tubular chimney a4. This chimney a4 is preferably provided as shown in the drawings, with a conical hood 0,5 which is suitably supported above the outer end of said chimney. At a point adjacent to the chimney a4, I provide the box a with a short vertical inlet b which communicates with the interior of said box.

b represents a suitable handle projecting from one of the longer sides of the box.

c represents an oil tank of less dimensions than the box a, but which is preferably of substantially the same height. This oil tank is adapted as shown, to be supported in aposition uadjacent to the rear end of the box a and has one of its ends jointedly connected with said box a through the medium of suitble hinge-plates c'.

, c? represents an oil pipe which leads from the tank c and runs parallel with the inner side of said tank to apoint past the unhinged end of the same, as shown. At a suitable point in the upper side of this tank, I provide an inlet opening c3 while at a point @4in said tank, I provide a suitable valve from which leads outward an air pipe c5, the latter being connected with a bulb c6 of the usual form through the medium of a tube c7. Upon the outer projecting end of the oil pipe c2 is supported a burner body d. This burner body which has a general tubular form andis open at its forward end, is provided in its rear end with a rearwardly projecting stem CZ through which is formed a longitudinal needle valve opening cl2 which leads to the interior of said burner. y

d3 represents a needle valve, the point of which is adapted to regulate the flow of oil or gas which is fed into said valve opening inthe manner hereinafter described. This burner body is provided on its upper and lower side with suitable openings indicated at d4, d5 and has suspended from its under side in communication with a portion ofthe opening d5, a suitable drip or lighting cup d6. Said burner body is also provided in its rear end with suitable openings indicated at d". In the construction of my improved burner, I provide said body with oppositely located lateral ribs or flanges e which extend substantially throughout the length of said body. Throughout these lateral projections, I provide channels or conduits e which are made to communicate at the forward end of the body through a connecting cond uit e2 which passes through an enlargement or head es formed over or upon the forward end of said burner body. The rear end of the outer conduit e communicates as shown atf in Fig. 4 of the drawings, with the valve opening d of the burner. The oil pipe c2 enters as shown in the drawings, the rear end of theinner conduit ethus formiuga communication between the tank c and the needle valve way, along the sides and over the burner body.

Projecting from the unhinged end and forward side of the tank c is an ear yor lugg through which is adapted to pass as shown in the drawings,a suitable set-screw g', said ear being adapted when said tank is swung in the position shown in dotted lines in Fig. l or in a position parallel with the rear end of the box to overlap the rear end of said box and admit of its being secured thereto by turning the set-screw g. When the oil tank is swung into this last named position, the greater portion of the burner body is as shown in the drawings, inserted within the mouth of the heat tube or flue a. The manner of utilizing and operating my improved warming device is as follows: Through the inlet b a suitable or desired amount of water is passed into the box or reservoir a, the water filling the space about the pipe contained therein. The oil tank c 1s swung outward as shown in full lines in Fig. l of the drawings, the Valve o4 opened and sufficient air injected into said. tank by the usual operation' of the bulb c6 to produce the desired pressure. Said air valve being closed the needle valve is turned outward suificiently to admit of a small portion of the oil contained within the pipe c2 and conduits e e2 to pass into the burner body and thence through the openings d5 into the cup d6. The oil thus contained in said cup being lighted, sufficient heat is imparted to the burner body and to the oil conducting flanges e, to generate gas from the oil contained therein. The needle valve is then opened and the gas allowed to escape into and through the burner body, where it is ignited. The tank c is then swung to the position shown in dotted lines in Fig. 1, until the burner body is within the heat Iiue of the box, resulting as will readily be seen in the iame which is driven outward from the forward end of the cylindrical burner being confined within said heat flue and extended by the draft therein toward the inner end of said flue. From the heat tube a', the

`gree of heat.

heat is carried through the pipe a2 and thence outward through the extension a3 and chimney 61,4. In order to facilitate the outward passage of the hot air thus generated, I preferably cause the pipe a2 to gradually incline The passage of the hot air through the pipe a2 must result as will readily be seen in the thorough heating of the water contained in the box about said pipe, and the water thus heated will serve to impart to said box a desirable heat which may be readily utilized as a foot-warming de vice or for other warming purposes.

From the construction herein shown and described, it will be seen that not only is a simple, reliable and effective means provided for imparting heat to the water contained in the box, but that my improved burner is of such construction and arrangement as to admit of the production of an elongated and forcible ame which will impart a high de- The perfect character of the flame produced by my improved burner is greatly enhanced by the fact, that the oil conducting conduits are arranged so as to pass not only along the sides of the burner body, but over said burner body, thus admitting of a high degree of heat being imparted to the gas contained in said conduits and in said gas being conducted to the needle valve in a perfectly dry condition.

It will be observed that in the construction herein shown, the entire body of the flame within the box or reservoir body and that the end and wall openings ofthe burner will serve asinlets for the proper amount of air toproduce perfect combustion.

It is obvious that my improved warming device may be utilized for many purposes, and that the same may be produced and operated at an exceedingly small expense.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is

In a foot warmer the combination with the water reservoir and heat conducting pipes passing therethrough, of an oil reservoir hinged to said water reservoir as described and an oil burner supported from and fed from said oil reservoir, said burner adapted to be projected into the mouth of the heat conducting pipe of the water reservoir by swinging said oil reservoir inward substantially as described.
